dated March 19, 1901.

Application filed November 16,1900. Serial No. 36,730. (Model.)

To all whom, t may concern:

Be it known that I, EDWARD M. HEYLMAN, of the city oi' Canton, county of Fulton, and State of illinois, have invented cert-ain new and useful Improvements in Oolter-Olamps, of which the following is a 'speciiication This invention provides acolter-clamp that may be adjusted by means of a single bolt to give the colter-shank all its Various positions. 1t is exemplihed in the structure hereinafter described and it is defined in the appended claim.

ln the drawings forming part of this specification, Figure lis a side elevation of the colter-shank clamp. Fig. 2 is a section through Fig. l on broken line ne.

The clamp for the colter-shank comprises a plate 13, a bar 24:, a disk 19, and a gib 14. The plate 13 is circularly recessed and undercut. It has lugs through which the securingbolts 17 and 1S extend, and it has teeth or corrugations 16 around the edge of its vcircular recess. The disk 19 is shaped to conform to the undercut recess of plate 13, and it has a lip 20 on one of its sides, which bears against a part of the corrugated surface of plate 13. Flanges 21 on the face of disk 19 are concaved to form bearings for the colter-shank 12. The gib 14 has one end shaped to bear against the corrugations of plate 137 and its other end 14E is shaped to embrace the colter-shank. bolt 22 extends through the disk 19 and through l the gib between the ends thereof, and a nut 23 on bolt 22 provides means for clamping the undercut edge of plate 13 disk and the gib, while at the same time clamping the colt-er-shank between bearings 21 of the disk and extension 111iL of the gib. The plate 13 is secured to a plow-beam 15,

the disk is turned to give the colter-shank the 4o required pitch withl relation to the beam, the colter-shank is turned on its longitudinal axis to bring the colter into proper position, and both adjustments are made secure by tightening the single bolt 22.

I claim- In a colter-clamp, the combination of a plate having a circular undercut recess, a disk bearing against the undercut surface of the plate and having depressed bearing-sur- 5o faces for the colter-shank, a gib bearing at outer surface of the undercut part of the plate and at the other end against the colter-shank and a bolt connecting the disk with the gib and providing means 55 for clamping the disk to the plate and the colter-shank to the disk.

In testimony whereof Isign my namein the presence of two subscribing witnesses.
